... will it go in flames?
Mercedes' first hybrid car looks set to become the first production motor with a lithium-ion battery when it debuts in Europe next summer. According the German car maker, the S400 BlueHybrid will use lithium-ion rather than the more commonplace nickel-metal hydride (NiMH) battery tech because of its much greater energy density …
Sounds like a bad idea to me -
LiON gets hot and is known to burn so put it in with the engine where it will get nice and toasty!
LiON has a pretty poor life - my leccy bikes LiON is rated to lose something over 30% of its power in a year and will need replacing after 2! Unlike the Prius NiMH batts that have lasted years and 100's thousands of miles.
No mpg improvement! And 50grams CO2 reduction... Couldn't they have acheived almost the same just by using the engine turning off tech at traffic lights etc?
Every little bit helps. I mean, think back just three short years ago - how many people even mentioned Global Warming/Climate Change in daily conversation, let alone think that electric car technology would be a necessary part of the solution ...... Well, I did - quite vocally in fact, but then I've always been ahead of the times. If only I could figure out how to get paid good money for that .....
Li-On battery - so what. The Merc 'leccy motor puts out a stunning [claimed] 20 bhp. Imagine how many toothbrushes that is in a row?!
The several year old Lexus RX400h (the UK's most popular Premium vehicle hybrid) manages to have one 'leccy motor feeding the front wheels (Wikipedia tells me it's rated at 167hp), AND another one feeding the back wheels, (providing another 68hp).
20 bhp seems like tokenism to me. Mercedes can claim big green credentials, "Hi tech battery first!" but their hybrid is milder than one of our recent frost-free, globally warmed winter days. Or am I being too cynical here?
Flame icon, 'cos that's what happens when you try to recharge a dense Li-On battery too quickly.
"Laptop battery tech" is simply a completely wrong description. Without further research I would guess that the cells used will be similar to these: http://saftbatteries.com/Produit_Large_VLM_cell_range_301_62/Default.aspx
These are high performance industrial cells which cannot be compared to the (China made) cells which can be found in laptops, electronical gadgets, or model aviation.
Which is why real aviation goes in a similar direction:
Worried about Li-Ion batteries because they catch fire on occasion?! Please!
Has everyone suddenly forgotten that petrol is extremely flammable? And we all drive around with several tens of litres of that in our cars every day without batting an eyelid!
Actually, the 'green' Merc is also going to need to have considerable quantities on board to feed it's thirsty engine anyways!
Seriously? Li-Ion batteries? Higher internal impedance and fewer recharge cycles than NiMH (not forgetting Lead-acid)? Mind you, if you have the dosh to run a Merc then you obviously have money to burn on a new battery pack every 12,000 miles.
And why only 20hp? Honda claim 80hp on their formula 1 car, a vehicle where space is at a much greater premium than a road car.
And lastly, why batteries? How about fly-wheels? No harmful chemicals, much lower maintenance, more reliable and infinite recharge cycles.
..clearly hasn't heard a C63AMG recently.
Youtube search it. Sounds far better in the flesh.
other than as a congestion charge workaround [see the Lexus 'Hybrids'] this is a load of toss. Merc should toss more money at getting more than [an already impressive, considering] 25+Mpg out of the six pot motor, and working on fuel efficiency out of their V12 engines, because other than 'congestion charge' zones, high-end hybrids are a fucking joke.
I'll get me coat - the ones with the Lotus keys in the pocket that I wish were mine. Mmm, 30+mpg for 0-60 in 4 seconds from a 1.8 four pot....
